`To all 'whom 'it may concern i Be it known that I, DUTEE IVILcox FLINT, a citizen of the United States, and resident ofthe city of Cranston, inthe county of Providence and State of Rhode Island, have invented certain new and useful Improvements in LiquidDispensing Apparatusj of which the following isa specification.

This invention relates to a liquid dispensing apparatus of the class more particularly adapted for supplying motor vehicles at the street curbing, and the invention has for its object to provide a main tank and an `auxiliary tank located inside of a building, or other convenient place clear of the side walk and to conductthe gasolene by gravity y through a supply pipe extending from this auxiliary tank to the edge of the street curbing, said pipebeing located underneath the side walk so as not to interfere thereover. p

' A further object of the invention is to provide means wherebythat portion of the pipe directly located beneath lthe side walk is automatically emptied after each supplying operation.

. Itis found in practice that the laws of some cities prohibit the placing of ak gaso- -lene tank or other obstruction at the edge of the street curbing, o r the carrying of` cans of the liquid across the walk, it is also I have so positioned and connected the .pipe

that it will be immediately and automatically emptied of its contents after each filling operation. I

With these and other objects in view, the

4invention c'onsists of certain novel features ofconstruction', as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1- is a diagrammatic View illustrating the general arrangementof my improved apparatusshoiving the supply pipe as extending to the curb beneath the side walk.. Fig. 2-

Fig. i+- is a sectional side elevation showing the sliding 'closure at the curb -for covering the aperture through which the hose is drawn when Vthe same is supply hoseafter' each supplying operation.

In carryingout my invention, ILhave provided a main tank 10 located in a cellar or excavation beneath the building in 'which the apparatus is stored and I have'provided an auxiliary tank l1 locatedr above the 'main tank and enough higher than the vehicles in the street to run the gasolene therefrom into the vehicle tank' by gravity. In supplying the auxiliary tank fromlthe main Y tank-I preferably provide a pump 12 driven by motor 13 which draws the gasolene up through the pipe 15 into this auxiliary talik. I have also provided a supply pipe 16 which extends downward-from the auxiliary tank and is connected at the point 17 with the valve 18 at the point 20 with the return pipe 19 leading back to the main tank 10. rl`he member 2l of this valve is shown as being in a plug form having a hollow stem I portion 22 to which the flexible supply hose pipe 23 is connected. This pipe, when not in use, hangs down in a. loop form to take up its slack and passes u p through the conduit 24, an its end which is supplied with the valve nozzle 2'5 is adapted to lie inside .of the'pocket 26 beneath the surface of the side walk completely out of the way.

In order to form a suitable pocket or inclosure for the opening through the side walk, necessary to permit the hose to be drawn out therethrough, I have provided a metal casing 27, which is preferably rectangular in shape having an opening at 28 suiicient to permit a plate 29 adapted to slide in grooves 30 to be moved back and permit the passage of the nozzle and hose when desired to be Ydrawn out for use and to slide forward and eifectuallyclose the opening when the hose is dropped back into. the pocket. Friction rolls .36 `are provided about the edge of the opening to prevent undue wear upon the hose While moving in and out. A' lock 3l is mounted in' the casing having a.

bolt 35 which is adapted to be moved to secure the plate when closed requiring a special key for releasing the same. This casing is set into the side walk Hush with its face at the curbing, and the closure is provided with a countei-weight 37 connected by cord 38 to automatically close the same as soon as the hose has been pushed back out of the way, thus preventing all possibilr ity of accident to passing pedestrians.

To assist in withdrawing the hose from the side walk back into the cellar after each operation, I have connected an arm 32 to theA rotatable portion of the valve to move with the hose and have connected the outer end of this arm to the hose by the strap 33, and on this arm I have mounted a counterweight 31 adapted to be adj usted along the bar and'attached where its weight will insure a quick withdrawal of the flexible pipe into the cellar, as soon as released .by the operator after the supplying of each vehicle. This return movement of the hose is facilitated by the placing of the conduit 24 on an incline, whereby the hose by its own weight would have a tendency to'fall back into the cellar. f

To the 'auxiliary tank 11, I have connected a glass tube 37 which is positioned in plain view of the customer and by which the exact level of -the liquid in the tank may be observed. On this tube, I have mounted a sliding gage 38 which may be adjusted along the tube and set in position so that it will assist in indicating to the customer the amount he is receiving.-

The operation of my improved invention.

may be more clearly described as follows--I The auxiliary tank is supplied from the main tank and is set at a height to supply the vehicles in the street by gravity through the pipe 16 and hose 23. When a vehicle drives up to the curb the attendant slides back the cover 30 from the casing which is set flush with the curbing and the side Walk, reaches -into a chamber 26 and draws out the supply nozzle end of the hose and positions the same into the tank ofthe waiting vehicle. The act of drawing the hose straightens 'its' loop portion in the cellar and through this movement operates the valve 18 to automatically close the return pipe 19 to the main tank and simultaneously open the passage-way from the supply plpe 16. The gasolene now runs from the auxiliary tank into the hose 23 and as soon as this hose is filled the attend-A ant sets the sliding scale so that the zero mark on the gage will correspond with the height of the liquid showing in the tube.

AThe amount drawn is then denoted on the gage by the falling of the liquid in the tank,

and when suiiicient ha-sloeen drawn for the customer, the valve at .the nozzle is closed and the semi-exible hose is drawn into position illustrated in Fig. 1. This action automatically closes thefsupply rom the auxiliary and opens the return to the main tank. The attendant now simply opens the valve at the supply nozzle and drops the same into its pocket the cover to which nnmediately -closes and the liquid from the hose drains back into the main tank. This operation is repeated as each customer presents his motor vehicle at the curbing. Y
